I just happen to be online here still so I'll reply: The desktop version of DeleD is no longer actively developed by anyone other than myself as far as I know (I've been working on the Lazarus port.) Ignore any references to pricing on the main page of Delgine.com. They're all very outdated. As far as prefabs........ I would think you could use them without issue, as the application itself is entirely open source. Don't quote me on that though. One of the original developers (Jeroen) still seems to monitor these forums, so maybe he can confirm this.

Indeed, you can just use every prefab that comes with DeleD for free. I just would like to see what you're using it for. I love to see a screenshot of your game/project etc! _________________Check out the gallery, our DeleD Wiki and Youtube videos!
